Evaluation of Mastoid Process as Sex Indicator in Modern White Americans using Geometric Morphometrics

Conventional methods for evaluating the mastoid as a sex indicator cannot determine whether mastoid shape is an independent and reliable sex indicator. Here, shape differences between the mastoids of 100 male and 100 female modern white Americans were statistically analyzed and visualized using the geometric morphometric method. Discriminant analysis was performed on mastoid size and shape. The relation between size and shape was analyzed to examine the effect of size on shape. In the results, mastoid size and shape were statistically significant sex indicators, while size factor explained 87.3% of the total variance of the shape variables. Nevertheless, females had relatively broader and shorter mastoid shape than males regardless of size, reflecting 12.7% of the total variance of the shape variables. In conclusion, mastoid size and shape were statistically significant sex indicators, while size may matter more in the mastoid than in other cranial parts in terms of sexual dimorphism.     

Astuteness in Commitment: Rwanda and UN Peacekeeping 1994–2014

Abstract

This article traces Rwanda’s history under German and Belgian colonialism, through independence and genocide to international respectability and membership of the Commonwealth. It examines Rwanda’s impressive contributions to United Nations and African Union peacekeeping forces. There is no single explanation for the magnitude of Rwanda’s contribution. It owes something to Rwanda’s commitment to ‘African solutions for African problems’. Deployment is relatively cheap and allows Rwanda to use its participation for political leverage in international affairs, to attract donors and to benefit financially. Peacekeeping is a factor in the astute foreign policy of Paul Kagame’s government that enhances its authority and stability at home and its prestige abroad.     

Gender,Ethnicity, and Education as Privileges: Exploring the Generalizability of the Existential Guilt Reaction

Two cross-sectional questionnaire studies were conducted to replicate and extend previous research on the existential guilt reaction. In Study I, gender was considered as a privilege. Male student participants (N = 141) were confronted with the low proportion of women in high-ranking positions and asked to appraise this situation. Self-reported behavior, behavioral intentions, and appeal to authorities aimed at advancing equal opportunities for both genders served as criterion variables. Path analyses were performed to explore the correlation structure among the variables. Self-reported behavior depended most strongly on behavioral intentions and on belief in control. Behavioral intentions depended most strongly on existential guilt. This effect accords to previous existential guilt research. Ethnicity and education were considered as privileges in Study II. Privileged Paraguayan students (N = 80) were confronted with the disadvantageous living conditions of Indians and Campesinos. They were asked to appraise the situation. Behavioral intentions and appeal to authorities directed at improving the living conditions of Indians and Campesinos served as criteria. As in Study I, existential guilt was the strongest predictor of behavioral intentions. Study II revealed the role of values in the process of existential guilt and prosocial behavior. This is a new research finding. Indirect effects of the two values of universalism and benevolence on behavioral intentions were obtained. The effect of universalism was mediated by existential guilt and moral outrage, the effect of benevolence was mediated by injustice and existential guilt. Tradition had a negative indirect effect on behavioral intentions. This effect was mediated by justification of deprivation and probably means that adherence to tradition eases the justification of traditionally existing social inequalities in a society.     

American Indian Tribes: ``Not as Belonging to But as Existing Within'

This article is an extended analysis of the historyand anomalies in the doctrine of American Indiantribal sovereignty. I explain that America gainedindependence, but took Indian land and colonized thetribes just as it had been colonized under theBritish. It asserted sovereignty for itself, butsubordinated the once independent tribes with aparadoxical semi-sovereign status as `dependentdomestic nations', all of this justified by the racialand cultural otherness of Indians. Using a Lacanianperspective, I show that America was founded on a`wound' or inconsistency at the heart of itsideological and constitutional order. In order torectify the inconsistencies that the initial `wound'produces, the law and political order havecontinuously had to adopt fictions (legal and racial). American law and policy has never been able to settlethe ambiguous doctrine of Indian sovereignty. As aresult, the law circles round and round in trying todefine it, and asserting and denying it, all in anunsuccessful attempt to make the constitutional orderwhole. It cannot succeed, however, since the ultimatesolution is an American sovereignty which, like God,admits of no limitation.

The dynamics of candidate evaluations and vote choice in 2008: looking to the past or future?

In this paper, we leverage a 10-wave election panel to examine the relative and dynamic effects of voter evaluations of Bush, Palin, Biden, McCain, and Obama in the 2008 presidential election. We show that the effects of these political figures on vote choice evolves through the campaign, with the predictive effects of President Bush declining after the nominees are known, and the effects of the candidates (and Palin), increasing towards Election Day. In evaluating the relative effects of these political figures on individual-level changes in vote choice during the fall campaign, we also find that evaluations of the candidates and Sarah Palin dwarf that of President Bush. Our results suggest a Bayesian model of voter decision making in which retrospective evaluations of the previous administration might provide a starting point for assessing the candidates, but prospective evaluations based on information learned during the campaign helps voters to update their candidate preference. Finally, we estimate the “Palin effect,” based on individual-level changes in favorability towards the vice-presidential nominee, and conclude that her campaign performance cost McCain just under 2% of the final vote share.

The weak domestic base of South Africa's good global citizenship

The self-appointed role of good international citizen that South Africa has played since 1994 is the external corollary of its supposed good governance at home. Weaknesses in domestic governance have, however, been evident since early in the life of democratic South Africa. These problems have become more acute, and internal dissatisfaction with and external awareness of ‘poor service delivery’ in South Africa have grown since 2009 when Jacob Zuma became president. The article illustrates that South Africa fails to meet core criteria of good governance and considers the implications of weak governance for the Republic's good international citizenship.     

Ancestral analysis of a Native American Ecuadorian family with congenital insensitivity to pain with anhidrosis

Congenital insensitivity to pain with anhidrosis (CIPA) is an extremely rare autosomal recessive disorder characterized by self-mutilating behavior, unexplained fever, inability to sweat and intellectual disability. CIPA pathogenesis is associated with genetic loss-of-function mutations of the NTRK1 gene, which is auto phosphorylated activating intracellular signaling transduction such as cell survival, growth and differentiation. CIPA occurs with an incidence of 1 in 125 million newborns, and only some hundreds of cases have been reported worldwide. Most of cases have been reported in Asian countries. Here, we estimate the ancestral proportions of a family with consanguinity background affected with CIPA, who carries the missense pathogenic mutations rs80356677 (Asp674Tyr) in the kinase domain of NTRK1 and rs324420 (Pro129Thr) in the FAAH gene. The ancestral proportion was calculated through 45 ancestry informative markers (AIMs) and the comparison was done through the Human Genome Diversity Project panel. The resulting allele frequencies in CIPA family indicate a prevalence of the Native American ancestral component with 87.9%, and minor proportion for the European (8.9%) and African (3%) components. In conclusion, the genetic variations expressing CIPA in a Native American Ecuadorian family could have been caused by the insertion of certain genetic characteristics, which have been passed down from common ancestors as consequence of migration towards South America.
